Researchers say peat covering the grave helped keep it intact over all these years.

Once work at the bottom of the ocean is done, Walsh-Haney says she will work with the Seminole and Miccosukee tribes on the best ways to preserve the underwater grave.

“What types of sands or sediments should we use to cap off the site to protect it. Will putting in buoys or pylons to alert boaters of this important site, how is that going to affect the preservation.”

State officials are keeping the exact location of the site a secret for now, and won’t disclose some of the artifacts that were found.

“Just the fact that I was able to be a part of something that was 7,000 years old is just absolutely unbelievable to me,” said Lopez.

It’s against the law for divers, boaters and anyone else to disturb the site or take anything from the site.
